Using the DIRBE/IRAS All-Sky Reddening Map To Select Low-Reddening Windows Near the Galactic Plane
Abstract
Recently Schlegel, Finkbeiner & Davis published an all-sky reddening map based on the COBE/DIRBE and IRAS/ISSA infrared sky surveys. Using the reddening map of Baade's Window and sample of 19 low-latitude (
|b|<5°
) Galactic globular clusters I find that the DIRBE/IRAS reddening map overestimates
E(B−V)
at low galactic latitudes by a factor of
∼1.35
. I also demonstrate the usefulness of this high resolution map for selecting low-reddening windows near the Galactic plane.
